LAMP.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed November 6, 1907. Serial No. 400,964.

To all whom it may concern:

Be it known that I, FRANCIS WILLIAM KEARSEY, a subject of the King ofGreat Britain, residing at the city and district of Montreal, in theProvince of Quebec, Canada, have invented certain new and usefulImprovements in Lamps; and I do hereby declare that the following is afull, clear, andexact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to lamp extinguishers.

The object of my invention is to provide a non-explosive lam adapted tobe automatically extinguishe when the lamp is tilted or overturned amore specific object of the invention is to provide gravity actuatedmeans for releasing a spring actuated extinguishing member, whichreleasing means is so arranged as to have a slight axial movement toinsure certainty of action when the lamp tilted in any direction.

My invention consists of the construction, combination, and arrangementof parts, as herein illustrated, described, and claimed.

In the accompanying drawings, forming part of this application, I haveillustrated one form of embodiment of my invention, in which drawingssimilar reference characters designate corresponding parts, and inwhich:

Figure 1 is a side elevation Fig. 2 is a horizontal section through thelamp guard, showing in plan the supporting plate and the extinguishingdevice, the chimney and guard being removed and, Fig. 3 is a sideelevation of the supporting plate and its connected parts, showing theguard in section.

Referring to the drawings, 1 designates a lamp font having the usualburner opening 2. A burner base 3 is provided with a screwthreadedportion adapted to engage the threads of the opening 2 and carries atubular wick well 4 which is extended upward for a relatively longdistance, so that its upper end is removed from the font to avoid anydanger of an accident from overheating. A plurality of arms 5 aresecured'to the burner ase 3 and carry on their upper ends a supportingplate 6 upon which the extinguishing apparatus hereinafter described ismounted. Suitable clips 7 may be used for attaching the members 5 to theplate 6 and burner base 3 if desired. The plate 6 is provided with aplurality of perforations 8 so as to permit a tree circulation of airfor the double purpose of keeping the wick well 0001 and for supplyingoxygen to maintain combustion of the Wick at the upper end of the well.

Disposed on the plate .6 is a guard 9 connected to said plate 6 as at 10by any suit able form of hinge, and held against lateral movementthereon by lugs 11 struck u from the plate. The guard 9 is made of sucient height to accommodate the extinguishing mechanism hereinafterdescribed, which is placed within the same so as to be protected.Secured on the supporting plate 6 is a bracket 12, or the like, adaptedto support a pintle 13. One side of the bracket 12 is formed by an arm14 bent up from the yoke 23 hereinafter described. The pintle 13pivotally supports the spring actuated extinguisher cap 15 by passingthrough the arm 16 of the same. The arm 16 is bent as at 17, and isprovided with an extension 18 on its lower end. A rod 19 is providedwith an eccentrically mounted weight 20 at its lower end and isprojected through the supporting plate 6. At a point just above the suportmg plate 6 the rod 19 is provided wlth a small coil 21 which restsupon said plate thus allowing a universal movement of the rod and itsattached weight.

In order to prevent rotation of the weight about the rod 19, said weightis provided with a flattened surface and the end of the rod is upturnedabout the weight as shown to engage the same. The rod 19 is set into theweight 20 at a point removed from the center of the same so that tiltingof the lamp will cause a slight axial movement to unseat the hooked end22 from the extension 18. The rod 19 is provided with a hodked upper end22, adapted to engage the extension 18 on the lower end of the arm 16and when the rod 19 is in a position of rest to maintain said arm in theposition shown in full lines in Fig. 1. Should the lamp be tilted orupset, movement of the rod 19 will release its hooked upper end from theextension 18 so that the arm 16 is free to move to its dotted lineposition shown in Fig. 1, thereby closing'the extinguisher cap 15 overthe wick and extinguishing the lamp.

For the purpose of actuating the arm 16 after it is released, there isdisposed on the supporting plate 6 a bent yoke 23 carrying one end ofthe pintle 13. its lower end 25 disposed between the arms and said yokeand held against the support- A spring 2 1 has i ing plate 6 by means ofa staple or the like, while its upper end engages under the bent portion17 of the arm 16 and when the arm 16 is released, as described, it isadapted to actuate the arm to its dotted line position (Fig. 1) so thatthe cap 15 moves to ex tinguish the wick. The preferred method ofmounting the spring 24 is to secure its lower end to the plate 6 by asuitable staple orthe like, pass it upward on the further side of thepintle and then bring it back over the pintle and downward beneath thebent portion 17 of the arm 16, all as clearly shown in Fig. 2. Thisholds the spring in position and at the same time insures its efiicientaction. In the operation of the invention, the wick well 4 beingrelatively long and the wick being lighted at its upper end the freecirculation of air as described keeps the wick well cool so that itsheat is not transmitted to the font 1, and danger of exploding andoverheating of the lamp is avoided. Tilting or overturning of the lampwill immediately release the arm 16 by the movement of the rod 19 underthe influence of the weight 20 so that the lighted wick is extinguishedby the cap 15 being actuated against it. The arms 5 are sufficientlyseparated on the side of the plate 6 where the weight is mounted, toallow free and unrestricted movement of the same, and, it will beobvious that they what I claim as new, and desire to secure by LettersPatent, is:

1: An extinguisher for lamps comprising a spring-actuated pivotallymounted cap, a pintle for supporting said cap, an arm extending fromsaid cap, a spring adapted to engage beneath said arm and to be retainedby said pintle, a rod mounted to have universal movement and providedwith a hook adapted to engage said arm to hold the cap elevated, and aweight mounted on said rod and adapted to actuate said rod to free the.cap to the action of its spring whenever the lamp is moved in anydirection from an upright position.

2. An extinguisher for lamps comprising a spring-actuated pivotallymounted cap, a pintle for supporting said cap, an arm extending'fromsaid cap, a spring adapted to engage beneath said arm and to be retainedby said pintle, a rod mounted to have universal movement and providedwith a hook adapted to engage said arm to hold the cap elevated, and aweight eccentrically mounted on said rod and adapted to actuate said rodto free the cap to the action of its spring whenever the lamp is movedin any direction from an upright position.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
